Not my first choice

I love Thomastik-Infields on my jazz and classical guitars but can't seem to find the right ones for my acoustic steel strings. Good sound and feel but entirely too much squeak for my style.

I love the sound of these strings. I have them on my Martin OM-28V. They have less overtones than, say, D'Addarios, and have a more focused fundamental tone for any note played. I think they sound wonderful. I feel that the excessive overtones (think D'Addario) don't sound that great. Even if you like D'Addarios, the initial rush of overtones only last a couple of weeks anyway. What you get with the Thomastik Spectrums is beautiful sounding fundamental tones with beautiful, but not jarring and excessive overtones. I love to listen to, say, a C chord strummed once ring out. The harmonics are great. Are they expensive? Yup. Are they worth it? Yup!

These have a nice warm sound. More costly then some other strings but I find they seem to last.

I'm using these on a nice hand built John David Scott guitar, and it likes these strings. They have great tone, very good volume and long sustain. Very nice.

Not real happy. I have the Martin dreadnought. At first the strings sounded OK. Not quite as loud or full or brilliant as I hoped. After a few weeks they did not go all tinny like most strings. Instead they sounded "hard" almost as thought the gauge got heavier. The are playable longer but I miss the first three weeks of brilliance and volume I get from D'Adarrio. Also the tuning key end of the 4th string was wound with a silk covering that caused the string to slip and de-tune at times. Why put silk there? I've never had a 4th string slip before. (the D string).

I used these strings as long ago as the 1970's when they were known as Dr. Thomastik's. They are very good strings and I haven't been disappointed. The only question I have about them in this day and age is the cost. Compared to other strings out there including Elixir's which I no longer use because the coating dulls the sound, Spectrums aren't cheap. But they do give a very bright smooth sound which is what I'm looking for. In this case the cost may be justified unless I find something cheaper that performs as well.

My Favorite strings by far

These are the perfect finger-style strings for me. They are light on the touch, but get impressive volume and tone that I don't get from most other strings.

I used them on a Collings OM for six years, and now on a Larrivee OM as well and they sound impressive on both. I tried using less expensive strings like EJ16's on the Larrivee, but the instant I put the TI's on I knew that had been a mistake. Well worth the price for me.

These strings are so light to the touch yet produce such a full sound on my Taylor 914. Go ahead and pay the little extra for a string you will be singing about too.

The intonation of this Spectrum Bronze strings are the best I have ever measured. They vibrate with at almost no fluxuating on the tuning gauge! When finger-picking, each note is musical and pure. I have to admit, these strings far exceeded my expectations. Thier enjoyment is worth the premium price.

TI Spectrum strings

No doubt the best strings I've ever put on my Martin 000-18 in 25 years of playing. In a class by themselves. Great picking and strumming. After putting TI's on, I stopped trying other brands.

Long sustain of fundamentals. Plenty of harmonics. All strings have nearly equal tension. Tone is consistent across the strings. Pitch is retained, so less frequent tuning. The high quality of manufacture is obvious. I use them on a Breedlove Pro Series dreadnought.

I started using these strings after I had used the PB-110's on my electric. They really make every note/chord seem to jump out my guitar. They are expensive but in my experience last at least twice as long as anything else I've ever used.
